JOSEPH J. WALSER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE GOSS PRINTING PRESS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CHASES.

To all 'whom t may concern Be it known that I, Josnrn J. VALsnR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chases, of which the following is a specifica-tion, reference being had to the accompanying drawings.

This invention relates to chases for use with flat bed print-ing presses, of the general type shown and described in application for Letters Patent of the United States, Serial No. 666,190, filed on December 16, 1911 by Villiam Evensen.

The object of my invention is to provide a new and improved construction by reason of which the adjacent sides of chases arranged side by side shall be strong enough to enable a proper locking of the forms in the chases without being so wide as to separate the forms in the adjacent chases unduly, as is set forth in application Serial No. 666,190, above mentioned.

A further object is to improve chases in sundry details hereinafter pointed out.

rIhe means by which I have accomplished these objects are illustrated in the accompanying drawings and hereinafter specifically described.

That which I believe to be new is set forth in the claims.

In the drawings, Figure 1 is a view of four chases abreast embodying one form of my improvements; Fig. 2 is an enlarged detail, being a cross-section taken on line 2--2 of Fig. 1, but showing the major portions of the forms cut away; Fig. 3 is an enlarged detail of a 'single chase, showing a modification of the form shown in Figs. 1 and 2, the chase of Fig. 3 corresponding to the second chase from the left in Fig. 2; and Figs. 4 and 5 are enlarged details, showing modified constructions applied to the intermediate chases.

Referring to Figs. 1 and 2, in which corresponding parts are indicated by like reference characters,-1O indicates a chase with the form 11 in position therein with a side stick 12 between the form and the side 13 of the chase, the head of the form resting directly against the head of the chase. 14e indicates a side stick along the opposite Side of the form and 15 indicates a foot stick along the lower edge of the form, both of which are in practice secured in position by means Specification of Letters Patent.

Application filed February 5, 1912.

Patented July 29, 1913.

Serial No. 675,506.

of quoins inserted between them and the corresponding sides of the chase, or in any other suitable manner, to hold the form properly locked in position. 16 indicates a second chase placed alongside of the chase 10 and holding a form 17.

18-19 indicate side sticks placed between the form and the sides 20-21 of the chase, and 22 indicates the foot stick. The side stick 13 is placed directly against the side 20, and the foot stick 22 is in practice tightened against the form by the insertion of suitable quoins, or by any other suitable means.

23 indicates pins screw-threaded into the side 21 of the chasn 16, each of which pins can be tightened against the side stick 19 for clamping the form 17 in position by means of a suitable groove 2e in the outer end thereof.

25-26 indicate chases placed alongside of the chases 10 and 16 and holding forms 27-28, respectively. The form 27 is located between side sticks 2930, the former of which lies against the side 31 of the chase 25 and the latter of which is adapted to be tightened against the form 27 by means of screws 32 carried by the side 33 of the chase 25 similar to the screws 23 of the chase 16. The form 23 is located between side sticks 34e-35, the former of which lies against the side 36 of the chase 26 and the latter of which is adapted to be tightened against the form by means of quoins in the well-known manner, as are also the foot-sticks 37-38 in the chases 25 and 26.

In Figs. 3, 4 and 5, each of which shows a distinct modification, the parts are indicated by reference characters corresponding to those used in Figs. 1 and 2, but with the addition of exponents. In Fig. 3, exponent a is used; in Fig. 1, exponent b; in

5, exponent c teferring to Fig. 3, 39 indicates a thin strip having secured to it by means of screws or in any other suitable manner two strips 40-4-.1 spaced apart along the edges of said strip 39. 42 indicates a thin strip iaving secured to it by means of screws or in any other suitable manner a strip 43 arranged along approximately the center of said strip 12.

While I prefer to use the construction shown in Figs. 1 and 2, in which the sides of the chase are formed of a single piece, still I do not limit myself to that specific construction except as hereinafter specifically claimed.

Figs. i and 5 show modified terms of construction for the two inner chases shown in Fig. 2. It will be understood that the inner sides of the end chases 10 and 26 will in practice be shaped to correspond to the outer edges oi' the intermediate chases, and it is not believed to be necessary to illustrate the modiiications further than is done.

As will be readily understood, by my construction the maximum width ot' the sides of adjacent chases is greater than could be used it such sides were rectangular in shape without greatly increasing the distance by which such sides would necessarily separate the 'terms contained in such adjacent chases. By this means, the lateral strength of the sides is made as great as possible consistent with the narrow side it is desirable to use. ln each of the forms l have provided virtually a tongue and groove construction by which one chase interlocks with the chase next to it.

Thile l have shown the outer edges of the sides of the chases tongued or grooved continuously from end to end, I do not wish to restrict myself to that particular construction, except as hereinafter specifically claimed, the essential. feature being that the side of one chase shall interlock with the adjacent side oi' the chase next to it whereby the sides may be made very strong against lateral pressure while at the same time taking up a minimum of space between the forms. Moreover, the construction by which the interlocking is secured also independently strengthens the side members of the chases. That is to say, While the laterally-extending rib of the side 13 of chase 10 and the two laterally-extending ribs otl the side 2l of the chase 16 cause such sides ot' chases 10 and 16 to interlock, still the rib upon the side 13 has an independent strengthening effect upon said side, and the two ribs upon the side 21 have an independcnt strengthening effect upon said side.

-I hereby speciiically disclaim as my invention the invention shown, described and claimed in and by the before mentioned application ot' rilliam Evensen, Serial No. (366,190, tiled December 1G, 1911.

lV hat l claim as my invention, and desire to secure by Letters Patent, is-

1. The combination ofa -plurality of chases arranged side by side, two adjacent sides ot said chases having interlocking portions which independently strengthen said sides against lateral pressure.

2. The combination of a plurality of chases arranged side by side, each two adjacent chases being interlocked along their sides whereby each of said sides is strengthened independently against lateral pressure.

3. The combination of a plurality ot chases arranged side by side, one of two adjacent sides of said chases being provided with a laterally-extending tongue and the other ot' said two adjacent sides being provided with a groove into which said tongue extends, whereby said sides are strengthened against lateral pressure.

Li. The combination of a plurality ot chases arranged side by side, one of two adjacent sidesof said chases being in the form of a channel-iron with the langesextending outward, and the other of said two adjacent sides being in the form of a T'iron with the stem extending outward into engagement wit-h said channel-iron whereby said sides are strengthened against lateral pressure.

5. The combination of two chases arranged side by side, the adjacent sides of which comprise two thin strips and two superposed strips therebetween, one ot' said superposed strips being formed separate from but secured to one of said first-nientioned strips, and the other of said superposed strips being' formed separate from but secured to the other of saicl irst-1ne1i tioned strips.

G. rlhe combination of two chases arranged side by side, the adjacent sides of which comprise two thin strips and three superposed strips therebetween, the middle one or' said three superposed strips `being formed separate from but secured to one of said first-mentioned strips, and the other two `ot' said superposed strips being formed separate from but secured to the other of said first-mentioned strips.

7. The combination of a plurality of chases arranged alongside ot each other and having abutting side portions which interlock with each other when said chases are associated on the press, whereby such side portions mutually reinforce each other.
